Hi,

I have a Sevylor HF280 inflatable. The directions suggest
only using a motor with a 15" shaft. The MK is 30". Where
do I measure to adjust the MK shaft down so that it would sit
in the water at the same depth as a typical 15" length motor,
or in other words the Sevylor motor that they sell.

The obvious answer might be at 15" I assume but I'm not
sure if it might actually be a bit lower since I would think
even with a 15" motor the attachment to the transom might be
lower than the very top of the whole unit.

Thanks,

Jesse


I agree with Steve, just get the prop below the water line enough to "bite"
(no cavitation) and high enough up not to bump into anymore stumps/brush
than necessary, and you will be set.

Before I got my little bass boat, I used to fish from a Coleman Crawdad
(circa 1986 or so) and just threw a 28# thrust, transom mount MK on it and
never adjusted it until I found shallow/stumpy water to fish. It (the MK's
motor head) probably went through the first two seasons a foot or more below
the water line with no problems. That is until I realized I needed to raise
it to take advantage of the shallow draft of the hull one day.
